Matrix CAMERA is an application that allows you to connect up to 255 devices*, in order to make videos obtained after the simultaneous triggering of each device's photographic recorder, giving the illusion of a video camera moving around a fixed action in time, or slowed to the extreme.
This visual effect is also called "bullet time".
To best use this application please follow these instructions, especially step 6:
1 - Identify a Wi-Fi network following its availability and proximity, or configure any of your devices in router mode (as allows, for example, the HTC One X - http://www.htc.com/us/support/htc-one/howto/365712.html), and connect each of them to the same Wi-Fi network.
2 - Once the Matrix CAMERA application has been installed on each device, start it up.
3 - A choice is therefore offered to you: "#1/#n?". This is the time to determine which device will be responsible to start shooting, by selecting the option "#1". Ensure that this choice corresponds to the most powerful device (with the best processor). Once this choice has been made, for all other devices the option "#n" will have to be chosen.
4 - A waiting process of about 1 to 2 minutes is necessary, the time in which each device is synchronized and identified by their position in the expected video. Then place the devices according to that rank around the action you want to shoot.
5 - Once positioned, it is the unit marked "#1" who is in charge of starting to record the video and taking simultaneous view. This is done in two steps: A first trigger is used to start recording. From that moment, a seven seconds countdown is displayed on the screen. After this time, the launch of the simultaneous shooting is automatically triggered.
6 - A second trigger launches simultaneous shooting, and then the classic video recording continues for three seconds. However, the shot will be truly effective one second after the trigger, so you are advised to trigger it manually one second before the action you want to freeze in time. This restriction is necessary to ensure a perfect simultaneity between each shot.
7 - Once you finish recording, a period of 1 to 4 minutes is necessary, the time in which the application creates video and transfers it to each device. Once this task is accomplished, the well produced video is added to your videos album, in the '/Movies/MCAM' folder (under the Android KitKat versions, it is saved in the application folder '/Android/data/com.studio.artaban.bullettime/files/MCAM'). You can also view the video directly from the application, and share it on your favorite social networks. However, be aware that this viewing may not match the actual saved video (display is faster or slower than the original video, with sound that is sometimes offbeat with the image), as the player is not standard.
8 - To make a new video, press the release button to return to step 4.
